DC Voltage Detector

DC Voltage Detector Operation Manual

Mode #: DCDTC

This Sigineer Power’s DC Voltage Detector is designed with 3 relays which will close or open at preset battery voltage to trigger the operation of Inverter Charger RLCD, 60/62.5hz inverter frequency switch and AC circuit breaker with remote control.

All the 3 relays are rated at 2 amps and operate within designed amp/voltage.

On the top cover, there are three buttons: “Set””Up”and ”Down”.

On the side, there is a 2-pin DIP switch, the nominal battery voltage is set through DIP switches , 0,0 for 12v / 1,0 for 24v / 1,1 for 48v

The voltage setting comes in increments of 0.1Vdc.

Note:

1: The low battery alarm is 0.5V higher than  “1 Low Battery Cutoff” at 12Vdc, 1Vdc at 24Vdc and 2Vdc at 48Vdc.

The high voltage alarm is 0.5V lower than “5 AC Charger Cutoff”, at 12Vdc, 1Vdc at 24Vdc and 2Vdc at 48Vdc.

The audio alarm is controlled by setting “1” and “5” only.

2: Setting 3 is lower than setting 5 in software. There is a locking between 1&2, 3&4, 5&6. Setting 2 is 1V lower than 1. Setting 3 is 1V higher than 4. Setting 5 is 1V higher than 6.

3: Low voltage alarm, beeps 0.5s at every 5 seconds; high voltage alarm, beeps 0.5s at every 2 seconds;

4: Setting 7(Screen Timeout) is for LED light time, resettable value from 10, 20, 30, 40, 50, 60 minutes to 99 which represent constantly light.

5: For relay C, there are three cables, white, black and red, the users can choose to two of them to flexibly control our circuit breaker.
